About Capacity.so
Capacity.so is an AI platform that helps developers and solo founders achieve production-ready application delivery without the manual overhead of boilerplate configuration.
Unlike traditional AI coding tools that rely on iterative prompting, Capacity.so enforces a disciplined spec-first methodology. Users begin by defining a comprehensive project brief and granular user stories which the agentic engine then processes. This structure ensures the generated TypeScript code adheres strictly to business logic. By maintaining a Global Context Engine, the platform maps the entire project architecture, enabling it to perform multi-file refactoring and resolve cross-file dependencies automatically.
The platform specializes in a modern tech stack centered on Next.js 14 and React 18. It provides native Supabase integration out of the box, handling everything from PostgreSQL schemas to authentication and real-time edge functions. For teams looking to scale beyond the platform, the Growth tier provides full codebase export, allowing for seamless deployment to Vercel or AWS with no vendor lock-in.
